1996 Corvette Grand Sport - Family Affair

This '96 Grand Sport Has A Rich Heritage All Its Own

As discussed at length in our December '05 issue, the '96 Grand Sport was a unique Corvette. Externally, the GS paid reverence to the Grand Sports from 1963. The car bore an Admiral Blue paint job with a wide white stripe covering the middle of the hood, roof, and rear portion of the body and included a pair of red hash marks placed over the left front fender. Red was used on the '96 GS as a styling cue to tie the two generations together. Unique Grand Sport badging was placed on each side of the hood above the side-fender vents, and a unique chrome-plated Corvette emblem was placed on the nose and gas lid. Interior color choices for the Grand Sport were limited to all black or a unique Torch Red and black combination, with red seats and trim and black carpeting with the Grand Sport name embroidered on the seat headrests.

All Grand Sport coupes used ZR-1-style, five-spoke rims with 275/40ZR17 rubber on the front and 315/35ZR17 on the rear. With all this rubber on the car, GM had to find a way to legally get the tires inside the wheelwells, so they decided to use an offset wheel and European flares already in the GM parts bin. The GS convertibles did not receive the fender flares and wider tires of the coupes. The wider tire/rim combination would not fit in a convertible (as a flat tire), so the convertibles were equipped with 255/45ZR17s in front and 285/45ZR17s out back to solve that problem.

From the beginning of the '96 GS project, everyone involved in the development of the car agreed the main ingredient should be about performance. To give the GS a unique engine of its own, the final solution was to redesign the current LT1 and offer it as a manual-transmission-only powerplant in all C4s, with the final engine named the LT4. This engine would come as standard equipment in all Grand Sports.

The LPE 383 conversion consisted of a LPE custom block preparation, a Lunati custom forged-steel stroker crank, Oliver billet rods, custom 10.8:1 forged aluminum pistons, and an LPE hydraulic roller cam. LPE also performed a CNC three-angle valve job on the stock GM heads, while new 2.00/1.56-inch LPE stainless valves were installed along with LPE double springs and titanium retainers. Comp Cams 1.6:1 S/S full roller rocker arms capped off the valvetrain. LPE/Hooker 131/44-inch shorty headers were installed to get the gases back to the CORSA exhaust system. A custom LPE 58mm high-flow billet throttle body topped off the mill. The modifications performed at Lingenfelter turned the already stout 330-horse 350 into a fire-breathing 450-horse 383ci supercar.

The Grand Sport was Dick's daily driver for eight months out of the year and is capable of adjusting anyone's blood pressure and heart rate quite quickly. Over the years, he made his annual pilgrimage to Corvettes at Carlisle; in 2000, the '96 was selected from more than 2,000 cars in the Corvette fun display to receive a Celebrity Pick award.
